Printing too fast, please control the speed between 60 ~
80mm /s.
The bell pully or bell might be loosened. Tighten them
up.
The stepper motor is missing steps. The current through
the motor might be too small so that the stepper motor
doesn’t have enough torque. Increase the output
voltage from the stepper driver to increase the power of
the stepper motor.
The stepper, stepper driver and the power supply might
be overheated. Overheating might affect the
performance of steppers.
The nozzle is not tightened. Heat up the nozzle
and remove the filament before
tightening the nozzle with a plier. Do not touch
the heated nozzle with your hand!
